Secondary glaucoma

Secondary glaucoma is a progressive optic nerve disorder which results in complete loss of vision.

Secondary glaucoma is a collection of progressive optic nerve disorders associated with a rise in intraocular pressure (IOP) which results in the loss of vision. In clinical settings, it is defined as the occurrence of IOP above 21 mmHg requiring the prescription of IOP-managing drugs.[1] It can be broadly divided into two subtypes: secondary open-angle glaucoma and secondary angle-closure glaucoma, depending on the closure of the angle between the cornea and the iris. Principal causes of secondary glaucoma include optic nerve trauma or damage,[2] eye disease, surgery, neovascularization,[3] tumours[4] and use of steroid and sulfa drugs.[2] Risk factors for secondary glaucoma include uveitis,[1] cataract surgery[5] and also intraocular tumours.[5] Common treatments are designed according to the type (open-angle or angle-closure) and the underlying causative condition, in addition to the consequent rise in IOP. These include drug therapy, the use of miotics, surgery or laser therapy.[6]
